The U.S. Army Corps of Engineers (USACE), in coordination with the Louisiana Department of Environmental Quality (LDEQ), is seeking public comment on the draft Environmental Assessment (EA) for the Port of Iberia navigation improvement project. The 30-day public review and comment period is open from August 24, 2026, to September 24, 2026.

Project Overview

The primary goal of the project is to enhance navigational efficiency and support economic development by deepening the channel connecting the Port of Iberia to the Gulf of Mexico. Key components of the proposed plan include:

• Channel Deepening: Providing a continuous channel at -16 feet Mean Lower Low Water (MLLW). This involves an initial deepening of 34 miles and subsequent maintenance dredging of up to 57.5 miles of the existing waterway.

• Waterways Affected: The project encompasses three main segments: the Commercial Canal, a portion of the Gulf Intracoastal Waterway (GIWW), and the Freshwater Bayou navigation channel.

• Infrastructure Improvements: The plan includes replacing the barge swing gates in the Freshwater Bayou Canal, placing 3,650 feet of rock revetment for shoreline protection, and relocating existing utilities.

• Environmental Restoration: Dredged material will be beneficially used to create and nourish approximately 1,944 acres of marsh and wetland habitat in degraded coastal areas.

A draft Environmental Assessment (EA) #510 and associated Finding of No Significant Impact (FONSI) titled "Atchafalaya Basin Protection Levees, Levees West of Berwick Bayou, East West Levee Tie-In" have been prepared by the U.S. Army Corps of Engineers, New Orleans District (CEMVN) to evaluate potential impacts associated with constructing an approximately 0.70-mile levee along the Gulf side of the Gulf Intracoastal Waterway (GIWW) while utilizing a contractor-furnished borrow area to construct it.

The levee traverses under the LA 317 bridge and ties in two sides of Ellerslie that are above the design levee elevation for this reach. The borrow area and the proposed levee work are both in the vicinity of St. Mary Parish, Louisiana. The details of these actions and other minor project changes are found in the Draft EA. 

The draft EA and FONSI are available online here.

Please review the documents and provide comments within 30 days of the date of this letter, Aug. 14, 2026.  A hard copy of the draft EA is available upon request. 

Comments should be mailed to the attention of:

The U.S. Army Corps of Engineers (USACE), New Orleans District, has published the Final Supplemental Environmental Impact Statement (FSEIS) titled "Morganza to the Gulf, Louisiana, Hurricane and Storm Damage Risk Reduction Project FSEIS.” It will be
posted at the following website for a 30-day notice period that will begin August 14, 2026 and end September 14, 2026: https://www.mvn.usace.army.mil/About/Projects/Morganza-to-the-Gulf/Documents/ .

The Recommended Plan presented in the FSEIS is a hurricane and storm damage risk reduction project involving an 86-mile alignment of earthen levees, floodgates, environmental water control structures, road gates, and fronting protection for existing
pump stations. The purpose of the project is to reduce the risk of damage caused by hurricane storm surges. The FSEIS evaluates proposed design changes to the authorized Morganza to the Gulf Project that consider existing local levee alignments and minimize impacts to sensitive habitats while meeting the 1 percent Annual Exceedance Probability Storm Surge Risk Reduction (100-year level of risk reduction). The FSEIS supplements the 2013 Final Post Authorization Change Report/Revised Programmatic EIS approved in the Chief’s Report signed on July 8, 2013. The project is needed because of the increasing susceptibility of coastal communities to storm surge due to wetland loss, sea level change, and subsidence.
